### Question: What to expect if I have Birthmarks-red  (Outlook/Prognosis)?
### Response: Birthmarks rarely cause problems, other than cosmetic changes. Many birthmarks go away on their own by the time a child is of school age, but some are permanent.
Strawberry hemangiomas usually grow quickly, stay the same size, and then go away. Ninety-five percent of strawberry hemangiomas disappear by the time the child is 9 years old. However, there may be some slight discoloration or puckering of the skin where a strawberry hemangioma was. Some cavernous hemangiomas disappear on their own, usually as a child approaches school age. Port wine stains are often permanent. Salmon patches often fade as the infant grows. Patches on the back of the neck may not fade, but are usually not noticeable as the hair grows.
